AUTOMOBILE-BUMPER. l

an automobile' frame with parts in sectionv and parts broken away; Fig. 2 is a section on an enlarged scale along line 2 2 of Fig. l; Fig. 3 is a section alongline4 3-3 of Fig.

2; and Fig. 4 is a section along line 4-4 ofl Fie. 2.

or the purpose of more clearly and easily illustrating my invention I have shown it applied to the front horns or ends A, A of an ordinary automobile-frame, the remainder of which is not shown, which is supported upon springs A1 and wheels A2.

The channel B formsv the usual bumper or guard across the front of the frame of the automobile and is slotted along its lower,

ange as indicated atB.` The thimble B2 is provided with laterally disposed ears B3 which Inaybegbolted-to the channel by the boltsB* in the slots Bl'asindicated to hold the thimble and guard in fixed position with respect one to the other. v that the thimble B2 is openonly at its rear end and `is preferably although not necessarily rounded ott' except Where it is in contact with the bumper and thereit must have two parallel sides at right angles to the square end to give a firm contact With the bumper. The interior of the thimble back of thebumper may be circular in cross section. Pins Bs are screw-threaded in the thimble B2 Vand project slightly thereinto separated -b an angle of 180.

The thim le B2 ismounted on the bracket .C which bracket is substantially tubular and provided with 'a reduced area C1` adjacent its forward end terminating in a projecting collar C2 which collar y'isslotted as at 3,03, these slots being so disposed with respect to the pins B5 that when the bracket and collar are in the assembled position the pins are located at a distance of 90 from the slots, thus providing for assembling by rotating I the thimble-"with respect to the bracket, slipf Specification of LettersPatent.

ping'the pins through the slots and'vthen rotating the bracket and thilnble to bring the slots andI pins out of alin'ement, thus holding the thimble in position limited!y as it is in its forward movement with respect to the bracket by the pins. The spring C* is i-nclosed` within the thimble at the end of the bracket, abutting at one endL on the col'lar C5 in the bracketand at the other end` on the front or bottom end of the thimble B2.

A saddle D having on its upper surfacea truncated, cylindrical trough or bearing surface ITl rests upon the upper surface of the frame horn, being in contact therewith along a line at either end as indicated at D2', D3

and out of contact at all other points. This Y saddle is, for the purpose of convenience and lightness and also to permit it to assume its position .independent of the presence of rivet heads in the frame, upwardly curved as indicated at D4 on both sides of the trough por- Ytion and downwardly curved as'indicated at D5 below the trough portion, thus making in effect two pockets between the saddle and the frame either one of which might contain the rivet head.

The bracket C terminates in an enlarged head or yoke E channelshaped and provided with the downwardly depending sides El, El on either side of the saddle. The lugs E2, E3 downwardlyy depending on the -inside of the channel are provided with curved bearing surfaces in engagement with either end of the trough or bearing in the saddle D. The ears E, E4 projecting` outwardly from either end of the walls E1, E1 are perforated as'indicated at E5 to engage the bolts E". l Cross pieces E7, E8 engage the lower sides of the frame horn, and, when the nuts E9 are tightened up on the bolts E, assist in holding the bracket and the saddle in iixed relation, thus holding the bumper in position. It will be noted that the curved bearing surface of the bumper on the saddle together with the two sets of bolts attaching it in position permit a certain degree of adyjustment of the bumper so that it may be made to assume a horizontal position independent ofthe curvature of the forward horns. The .pressure 'of impact on the bumper it will` be noted 4will be thus carried llO v yi

automobile frames ,normally increase in depth from the end rearwardly, there is no dangerous tendency toward rearward movement of the bumper.

By carrying the bumper away end of the horn where the horn is thicker and where'the curvature lis likely to be slightly less, it will be noted that the tendency to bend the frame when heavy blows are given to the bumper is thereby greatly minimized, and one great disadvantage in the Well known type of bumper where the "load is applied to the end of the frame is thus obviated.

It will. be evident-that, while I have shown` in my drawing an operative device, still many changes might be made in size, shape and arrangement of parts without departing materially' from the spirit of my inven-4 tion.' I Wish',therefore, that my drawing be regarded as in a sense diagrammatic.

- bracket, a 'bumper member carried by the thimble and aA compressible'member located Within the thimble and the bracket abutting at one end on the thimble and at thc other end onthe bracket, said bracket being re-` ,duced beneath the thimble and provided with 4a slotted collar about its forward end and pins carried by thethimble and adapted to abut'upon the collar, the. relative positions of said pins and slots being such that from the y when in the assembled relationA the pins are out of line with the slots. v

3. In an automobile bumper a saddle having a cylindrialbearing thereonand resting upon the automobile frame, a bumper bracket, a pair of lugs downwardly projecting from the bumper bracket on either side and provided with cylindricalsurfaces in v engagement with said cylindrical bearing and means for holding said saddle and saidy bracket together in fixed position on the automobile frame.

a. In an automobile bumper, a cradle resting upon the automobile frame, a bumper bracket rotatable vwith respect to and resting upon the cradle, and means in engagement With the bracket and adjacent and out of contact with the cradle for holding the bumper bracket and cradle in-ixed position with respect each to the other and each to the frame.

' 5. In an automobile bumper, a cradle free -to rest upon the automobile frame, a 'segmental, cylindrical bearing on said cradle, a bumper bracket and a segmental, cylindrical ,projection thereon engaging said bearing on said cradle and means4 adjacent and out of Contact with said cradle for holding said vbracket in fixed relation to said cradle and bearingand to the automobile frame.`

6. An automobile bumper comprising a cradle resting upon the automobile frame with bearing surface thereon, a bumper` bracket engaging said bearing; surface, a yoke on said bracket inclosmg and covering said cradle and means for holding said yoke' in .fixed position with respect totheframe independent of said cradle.

In testimony-whereof, I alix my signature in the presence of two witnesses this twelfth day 'of March 1913.
